Kurz gesagt, zuerst - Ich erhalte diese Ausnahmemeldung:Doppelte Annotationsfehler - aber wo?
serverError: class javax.faces.el.EvaluationException Duplicate annotation for class: interface javax.validation.constraints.Size: @javax.validation.constraints.Size(groups=[], min=0, message={javax.validation.constraints.Size.message}, payload=[], max=128)
Mein Code besteht aus 1 Entity-Klasse für eine Tabelle, eine EJB, ein 'Business-Class' und eine JSF-Seite; Die Ausnahme tritt auf, wenn ich EntityManager.merge() aufruft. Es gibt nur 1 Anmerkung mit ‚max = 128‘ drin:
@Size(max = 128)
@Column(name = "name")
private String name;
der einzigen Ort mit duplizierten Anmerkungen ist:
@Entity
@Table(name = "attributes", schema = "office_db")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "Attributes.findAll", query = "SELECT a FROM Attributes a"),
@NamedQuery(name = "Attributes.findById", query = "SELECT a FROM Attributes a WHERE a.id = :id"),
@NamedQuery(name = "Attributes.findByName", query = "SELECT a FROM Attributes a WHERE a.name = :name"),
@NamedQuery(name = "Attributes.findByType", query = "SELECT a FROM Attributes a where a.type.id = :type")
})
aber ich denke, dass legit sein sollte, wie es von Netbeans generiert wurde 8.2 aus der Datenbanktabelle.
Jetzt einige weitere Details. Zunächst wird die Tabelle:
mysql> show create table attributes\G
*************************** 1. row ***************************
Table: attributes
Create Table: CREATE TABLE `attributes` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`parent` int(11) DEFAULT NULL,
`type` int(11) DEFAULT NULL,
`name` varchar(128) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `parent_ix` (`parent`),
KEY `type_ix` (`type`),
CONSTRAINT `attributes_parent_fk` FOREIGN KEY (`parent`) REFERENCES `attributes` (`id`),
CONSTRAINT `attributes_type_fk` FOREIGN KEY (`type`) REFERENCES `attributes` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1301 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
1 row in set (0.03 sec)
Als nächstes wird der Entity-Klasse:
import (...stuff...)
@Entity
@Table(name = "attributes")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "Attributes.findAll", query = "SELECT a FROM Attributes a"),
@NamedQuery(name = "Attributes.findById", query = "SELECT a FROM Attributes a WHERE a.id = :id"),

Die EJB oder Session-Klasse:

Das Geschäft oder Controller-Klasse:

Warum nicht die tatsächliche Ausnahme + Stack-Trace post und dann können die Leute sehen, woher es kommt, anstatt – DN1
gut zu erraten, zwei Gründe, wirklich. Erstens wollte ich hier keine Codewand wegwerfen, wenn es kein Interesse gab, und zweitens mag ich es nicht, wenn Leute ihren Code einfach ablegen und ihn darum bitten, ihn zu reparieren. Ich wollte das nicht tun. Ich möchte wirklich verstehen, was auf einer tieferen Ebene geschieht, und das Problem, obwohl wichtig, ist nicht das einzige, was für mich wichtig ist. Ich werde mehr Details in einer Antwort posten - danke für die Nachfrage. – j4nd3r53n
Tatsächlich habe ich gerade festgestellt, dass das Hinzufügen von mehr Details in einer Antwort nicht der richtige Weg ist, also werde ich stattdessen eine Bearbeitung hinzufügen – j4nd3r53n
